 high power argon laser replacement 488 515 532 nm

 

Drop-in replacement of Argon lasers (488/515nm) which are often used in bio-photonics application. Azur Light Systems lasers offer one of the best power and pointing stability on the market, are very low-noise, and don’t need any cooling system for the laser head. Multiple visible wavelengths are available (488, 515 or 532nm). Possibility of single mode output fiber coupling for every laser up to 1-5W (visible) and 50W (IR).  see Azur Light Systems visible fiber lasers

Laser Doppler Velocimetry

Laser Doppler velocimetry (LDV) , also known as laser Doppler anemometry (LDA), is the technique of using the Doppler shift in a laser beam to measure the velocity in transparent or semi-transparent fluid flows, or the linear or vibratory motion of opaque, reflecting, surfaces. The measurement with LDA is absolute linear with velocity and requires no pre-calibration. See  Azur Light Systems-Visible (ALS Ocean)

High efficiency Laser pumping

 

High efficiency Laser pumping high brightness 515 nm

 

Azur Light Systems technology  provides high brigthness optical pumping at 976nm, which can greatly improve Ytterbium pumping efficiency.

Ti-Sa pumping is 15% more efficient at 515nm (Argon laser) than at 532nm (classical pumping ). Our best standard solution for Ti-Sa pumping is an ultra-low noise single frequency10W@515nm laserwith a cooler-less laser head. Lower maintenance cost and better performances than DPSS or OPSL technologies. See ALS Visible, ALS IR

Laser cooling refers to a number of techniques in which atomic and molecular samples are cooled down to near absolute zero through the interaction with one or more laser fields.

Exotics wavelengths available - Possibility to choose the central wavelength thanks to the MOPA configuration, which can be of an interest to perfectly match several atoms rays.

Very high pointing stability to meet the highest research requirements.

Cooler-less laser head  no vibration for a better stability.

Atoms cooling requires single frequency to match the atoms ray, but atoms trapping doesn’t need single frequency (interest only for power/poiting stability) even if users are most likely to choose our single frequency version to get better performances thanks to their ultra-low noise level.

In biotechnology, flow cytometry is a laser-based, biophysical technology employed in cell counting, cell sorting, biomarker detection and protein engineering, by suspending cells in a stream of fluid and passing them by an electronic detection apparatus. It allows simultaneous multiparametric analysis of the physical and chemical characteristics of up to thousands of particles per second. See ALS Visible (ALS Blue)

High quality hologram recording is achieved when using high beam pointing stability along with super stable output power and a high polarization ratio. Single frequency versions (standard < 200kHz but possibility to supply higher coherence length). Ultra-low drift of central wavelength over time (<75MHz over 8 hours an T° variation of 3°C). Ultra-low noise. Multiple visible wavelengths available.

Very high pointing stability, best on the market (<0.5µrad/°C  ). Lower maintenance cost, longer life…

Turbulence, hydrodynamic instabilities, two-phased flows, environmental fluid mechanics, internal aerodynamics,  aeroacoustics, acoustic propagation.

To acheive high quality measurements on those interference/image based techniques the laser setup need to provide

power intensity stabilization over a long period of time, very high pointing stability, stable high polarization ratio (for interference fringe contrast)  to meet the most accurate requirements.

Cooler-less laser head (no vibration) for a better stability(better performances, lower maintenance cost, ease of use, no misalignement, longer lifetime are also to be considered in the industry QC and QA methods. See ALS Ocean
